Title: Improvements in or relating to oxygen breathing apparatus
Inventor: HAMILTON WILLIAM CRAIG
IPC: A62B7/08
Filed: 1954-10-08
Abstract: 754,305. Respiratory appliances. MINE SAFETY APPLIANCES CO. Oct. 8, 1954, No. 29122/54. Class 81(2). The oxygen generating canister of a breathing apparatus is held in position against an admission valve by a pair of spaced arms which support it by pressing upwards under a lip formed on the neck of the .canister. The metal guard 1 for the canister 2 carries a valve assembly 8 at its upper end and the valve therein comprises a vertically sliding member so arranged that when a canister is in position, direct communication with the system is provided, while when there is no canister, the outlet is closed. On the front of the body 1 a handle 32 is pivoted at 30 and this carries a stop 47 so that when a canister has been pushed up into the holder past a spring catch 44, it can go no further until actually required for use. When so required, a catch 39 is released and the handle 32 is pulled outwards so as to withdraw the stop and to lower arms 50, carrying bosses 54. clear of the canister, which is then pressed fully upwards. Its protective cover is thereupon broken by the pivoted projection 25 and the lip 27 engages against a conical skirt of the valve member, against which it is sealed by a rubber ring 28. The upward movement of the skirt opens the valve to establish communication with the breathing apparatus. With the canister in this position the handle 32 is again lowered so that the bosses 54 come up under the lip 27 and hold it in position. The arms 50 are connected by spring means 53 with the handle to allow for variations in size of canisters and to ensure positive location against the valve body. When there is no canister or when one is in the " ready " position shown, the bosses 54 lift the valve slightly off its seating so that neither the upper nor the lower seating is engaged and no deterioration can result.

Abstract: 687,309. Extracting studs from shafts. LA BOUR CO., Inc. Nov. 29, 1950 [Oct. 9, 1950], No. 29299/50. Class 61 (iii). [Also in Group XXIV] The shaft 5 of a rotary impeller 6' is integral with a stud 7 fitting into a co-operating socket in a driving shaft 2, the assembly being mounted in ball-bearings in a housing 35. The two shafts 5, 2 are connected by a Woodruff key 16 engaging a keyway in the wall of the socket and by a screwed pin 23 in a transverse bore in the stud 7 engaging the shoulder of a hole 27. The pin 23 is of such a length that it may be withdrawn completely into the transverse bore. When separating the two shafts, the pin 23 is withdrawn into the transverse bore by means of a wrench inserted through a hole 34 in the housing 35 engaging a hexagonal socket in one of its ends. A drift 32 is then inserted through the hole 34 and through one of two holes 30 in the socket, offset by 90 degrees from the hole 27 and removed axially therefrom, the wedging action of the tool urging the stud 7 axially out of the socket. The drift 32 is' provided with longitudinal bars 33 which engage with the wall of the housing 35 when the limit of travel has been reached, so that unnecessary pounding of the drift may be avoided. Specification 588,939, [Group XXVI], and U.S.A. Specification 2,134,255 are referred to.

Patent GB-1007492-A (GB)
Title: Improved carbon black process
IPC: C09C1/50
Filed: 1962-08-03
Abstract: Carbon blacks having desired physical properties are obtained by adding elemental tin or a tin compound to the reaction zone of a carbon black process whereby a carbon black containing 100-200,000 parts of elemental tin per million parts of carbon is produced. 250-300,000 parts by weight of tin per million parts by weight of coke fuel are used.  Physical properties affected are, particle size, oil absorption, curing speed, arrangement of particles, and blackness.  Preferred tin additives are the chlorides, sulphates and carbonates, however any tin compound soluble dispersable or suspendable in water, aqueous media or organic media (which may be the hydrocarbon make fuel) may be used.  Elemental tin is used in powder or fine wire form and is vaporized in the heated reaction zone.  According to examples acetylene was burnt in air whilst the additives, tin chloride, sulphate, chromate, and stannous acetate were added.  The carbon black produced may be used in rubbers, plastics, lacquers, inks, paints and dyes.

Title: Improvements in fastening devices for engine cowlings, cover plates and like purposes
IPC: F16B5/10
Filed: 1944-11-15
Abstract: 622,992. Stud and socket fastenings. SIMMONS, C. A. Nov. 15, 1944, No. 29893/47. Divided out of 622,728. [Class 44] A stud and socket fastening for securing an outer plate to an inner structure is provided with a threaded receptacle supporting part having threads extending close to the outer plate, with which threads the hole in the outer plate is aligned, comprising a receptacle or socket element having threads engageable with the threads on the supporting part, and a short stud element disposable in the hole and carrying means engageable with the plate to hold the stud element against inward movement relative to the plate. The fastener is adapted to hold together an outer plate 10 and an inner plate 11, Fig. 1. A receptacle support 19, 20 is secured to the inner plate 11, and has an internally threaded part 20, with diametrically opposed bores 21. An externally tubular receptacle or socket 24 screws into the part 20, and is provided with an uneven number of external longitudinal grooves 25 narrower than the diameter of the bores 21, and a bail shaped spring locking strip 26 is curved around the part 20 and has inturned ends 27 adapted to pass through bores 21 into one of the grooves 25. When turned into the position of Fig. 1, the ends 27 cam out of grooves 25 and unlock the socket. The inner face of the socket is formed with opposite ledges 30, Fig. 4, each having a hollow recess 31 and a stop and cam faces 33 to lead the pins of the stud, which enter through opposite passages 34 between the ledges 30, into the recesses 31 on rotation of the stud. The latter may be of the construction described in Specification 622,728 and fastening is effected in the usual way, socket 24 being previously adjusted to the required position and locked by the bail 26. The relative positions of the parts and the direction of the threads on the socket are such that when the latter is not locked, rotation of the stud will cause the socket to move inwardly and force flange 44 of the lock member against flange 38 of the stud to draw plates 10, 11, together. Various forms of socket member are described. Fig. 6 shows a form in which the support 19a, 20a has the tubular portion 20a reversed and disposed in openings in plates 11b, 11c which form parts of a thick inner member. The support may be omitted, and the socket 24, Fig. 7, screwed directly into the plate 11d and locked by a nut 19d. In the form shown in Fig. 10, the socket 24 is screwed into a cup shaped support which has a threaded extension 19 adapted to screw into one of the members to be joined. In a similar form, the support and the socket are made integral. In place of a spring stud, a stud 35k, Fig. 14, with helical bayonet slots 30k may be used, engaging a fixed bar 29k secured across the socket 24k.

Title: Method of and apparatus for making a hooked pile fabric
IPC: D06C29/00
Filed: 1955-10-25
Abstract: 786,921. Finishing fabrics. FORSTER, K. Oct. 25, 1955 [Oct. 26, 1954], No. 30422/55. Class 42 (1). [Also in Group IX] A hooked pile fabric is formed by weaving into a foundation fabric pile - forming synthetic fibres which extend from the foundation fabric in an upright direction and are of substantially equal length, and subjecting the fibres to axial pressure accompanied by heating to effect bending of the tips and plastic deformation thereof to hook shape. As shown, the pile fabric 1, Fig. 1, is drawn over a slide 3 beneath a roll 4 driven at a peripheral speed equal to the fabric speed. The surface of roll 4 is honeycombed with hemispherical concavities. The roll is adjusted so that the tips of the pile threads 11, Fig. 2, strike against the concavities and are bent to form hooks in random directions. Roll 4 is heated so as to soften the pile tips, the lower part of the pile and the foundation fabric being cooled by air drawn through slots 7 in slide 3 and through the fabric. Slots 7 are enlarged towards the exit side of the appartus so that the hooks 13 are cooled and set. The pile fibres may be of nylon or perlon; they may be welded or cemented at the base to the foundation fabric by thermal or chemical treatment applied to the foundation fabric from the reverse side prior to or after formation of the hooks.
